The best part about this product was that it gave me an option to test real time scenarios without actually writing any code myself! I had no idea how exactly will my application behave with respect of some third party api call in production environment so i thought its better if we have something like fake server running our tests instead of developing them using normal browser or emulator tools as well!! So far everything seems good but there are nothing special here too much over priced compared other products outthere.
It would be great If they can provide us free versions at least during beta period because currently you cant use all features unless u buy full version. ! Also please try their demo first before buying anything else just go through couple simple examples available online then decide whether your app behavior matches what expected from client side point view otherwise dont waste ur money by going ahead blindly. !!
